House of Darkness
The House of Darkness was directed by D.W. Griffith for the Biograph Company in 1913. Its theme is how music soothes the insane mind. It deals with an escaped mental patient who threatens a woman with a gun, but backs off when she plays the piano for him. It is sentimental ad many of Griffith's films are but the acting is a bit subdued for the silent film of the period. It is worth a look.
